[0001] 本申请要求于2012年3月9日提交的美国专利申请13/417, 155和于2012年3 月15日提交的美国专利申请13/421,703的优先权,每个专利申请据此全文以引用方式并入本文。 [0001] This application claims priority to US Patent Application No. 2012, filed March 9 13/417, 155 and US patent on March 15, 2012, filed 13 / 421,703, each patent application, according to It is hereby incorporated by reference herein.

背景技术 Background technique

[0002] 本发明整体涉及电子设备,并且更具体地,涉及具有显示器和相关联背光结构的电子设备。 [0002] The present invention generally relates to electronic devices and, more particularly, relates to an electronic device having a display and associated backlight structures.

[0003] 电子设备(诸如计算机和蜂窝电话)具有显示器。 [0003] Electronic devices (such as computers and cellular phones) having a display. 一些显示器(诸如等离子体显示器和有机发光二极管显示器)具有生成光的显示器像素阵列。 Some displays (such as a plasma display and an organic light emitting diode display) having an array of display pixels to generate light. 在这种类型的显示器中, 背光并非必要的,因为显示器像素自身产生光。 In this type of display, a backlight is not necessary, since the display pixels generate light itself. 其他显示器包含被动显示器像素,其可改变透射穿过显示器以对用户显示信息的光量,但自身并不产生光。 Other passive displays comprising display pixels, which may change the amount of light transmitted through the display to display information to a user, but do not produce their own light. 因此,常常需要为具有被动显示器像素的显示器提供背光。 Thus, it is often desirable to provide a display having a backlight of a passive display pixels.

[0004] 在用于显示器的一种典型背光组件中,发光二极管带沿导光板的边缘定位。 [0004] In an exemplary backlight assembly for a display, a light emitting diode strip along the edge of the light guide plate is positioned. 光从该发光二极管带发射到导光板内,并且导光板用于将光分布于显示器上。 Light is emitted from the LED into the light guide strip and the guide plate for the light distribution on the display. 发光二极管带常常安装在显示器的非有效的显示部分的下方。 LED tapes often mounted below the non-effective display portion of the display.

[0005] 要确保在导光板边缘处存在足够空间以容纳发光二极管就可能需要在显示器的边界处有大量非有效的显示区域。 [0005] To ensure that there is sufficient space at the edges of the light guide plate to accommodate the light emitting diode may require a large number of non-effective display region of the display at the boundary. 这种类型的宽的非有效的显示边界可能在美学上无吸引力,并且可减少可用于对用户显示图像的有效显示区域的量。 Wide non-effective boundary of the display of this type may be aesthetically unappealing and may reduce the amount available for the user to display images of the effective display region.

[0006]在用于显示器的一种典型背光组件中,使用导光板来分布由光源(诸如发光二极管光源)生成的背光。 [0006] In an exemplary backlight assembly for a display using a backlight light guide plate to distribute generated by a light source (such as light emitting diode light source). 光学膜(诸如漫射层和增亮膜)可置于导光板顶部。 An optical film (such as a diffuser layer and a brightness enhancing film) can be placed on top of the light guide plate. 可在导光板下方形成反射器以提高背光效率。 The reflector may be formed under the light guide to improve the efficiency of the backlight.

[0007] 为了提供令人满意的背光,可能需要将一个或多个发光二极管带定位于导光板的边缘上。 [0007] In order to provide a satisfactory backlight, you may require one or more light emitting diodes located on the edge of the belt guide plate. 可通过将一行发光二极管安装到柔性电路上来形成发光二极管光带。 By mounting the light emitting diode to line up the flexible circuit is formed with a light emitting diode. 光带通常附接于导光板的边缘,以使得发光二极管可将光引导至导光板内。 Optical tape is generally attached to the light guide plate edge, so that the light emitting diode can be guided to the light guide plate.

[0008]在一种理想的光带中,发光二极管相互对准,以使得每个发光二极管可物理地接触导光板。 [0008] In an ideal band of light emitting diodes aligned with each other, so that each light emitting diode may physically contact the light guide plate. 然而,在一行发光二极管中常存在导致不对准的放置变化。 However, often exist in a row light emitting diode placement variations result in misalignment. 如果不小心,则这种类型的不对准可导致发光二极管和导光板之间的气隙。 If not careful, then this type of misalignment can result in an air gap between the light emitting diode and the light guide plate. 气隙的存在可对背光效率具有不利影响。 The air gap may have an adverse effect on the efficiency of the backlight. 较差的背光效率又可降低电力消耗效率,并且可降低电子设备中的电池寿命。 Poor efficiency of the backlight in turn reduce power consumption efficiency, and may reduce the battery life of the electronic device.

[0009] 因此将需要能够提供具有用于背光显示器的改进布置的电子设备。 [0009] Thus the need to be able to provide an electronic apparatus having an improved arrangement for a backlit display.

[0088] 基板60可耦接至印刷电路,诸如印刷电路62。 [0088] The substrate 60 may be coupled to a printed circuit, such as a printed circuit 62. 印刷电路62可为由诸如玻璃纤维填充的环氧树脂(例如FR4)这样的材料形成的刚性印刷电路板,可为由一个或多个柔性聚合物(诸如聚酰亚胺)片材形成的柔性印刷电路("柔性电路"),或可由诸如陶瓷、塑料、 玻璃等这样的材料形成。 The printed circuit 62 may be a glass-filled epoxy such as (e.g., FR4) rigid printed circuit board formed of such a material, may be by one or more flexible polymers (such as polyimide) is formed of a flexible sheet a printed circuit ( "flex circuit"), or may be a material such as ceramic, plastic, glass, or the like. 如果需要,印刷电路62可由刚性层和柔性层的组合形成(有时称为"刚性-柔性"印刷电路)。 If desired, the printed circuit 62 by a combination of rigid and flexible layer forming layer (sometimes referred to as "rigid - flexible" printed circuit). 可使用连接器、使用焊料或使用任何其他合适类型的附接方法将基板60附接至印刷电路62。 The connector may be used, using solder or using any other suitable type of attachment method for attaching the substrate 60 to the printed circuit 62.

[0089]集成电路、分立组件(诸如电阻器、电容器和电感器)和其他电子部件(诸如组件64)可安装至印刷电路62。 [0089] integrated circuits, discrete components (such as resistors, capacitors and inductors), and other electronic components (such as assembly 64) can be mounted to the printed circuit 62. 如果需要,组件(诸如组件64)可用于经由迹线66向光源38 提供控制信号(作为例子)。 If desired, components (such as assembly 64) can be used to trace 66 provides a control signal to the light source 38 via the (as an example).

[0090]在操作期间,光源38可用于将光68发射至背光结构30内(例如,至图5的导光板32内)。 [0090] During operation, light source 38 may be used to transmit light 68 (e.g. the, to the light guide plate 5 in FIG. 32) within the backlight structure 30. 背光结构30可用于在方向z上将光68均勻地分布于显不层58上。 Backlight structures 30 may be used in the z-direction on the light 68 is not substantially uniformly distributed in the layer 58.

[0091]在一种常规背光组件中,发光二极管沿导光板的边缘定位并且通常位于显示器的非有效的显示部分下方。 [0091] In a conventional backlight assembly, the light emitting diode along the edge of the light guide plate and positioned below the non-effective display portion of the display is usually located. 在导光板的边缘处容纳发光二极管可能需要大量非有效的显示区域。 Receiving the light guide plate at an edge of the light emitting diode may require a large amount of non-effective display region. 例如,在导光板的边缘处可需要宽度诸如宽度W以容纳发光二极管。 For example, at the edge of the light guide plate may be required to accommodate the width W of the width such as light emitting diodes. 另外,为使来自分立光源的光变得均匀,需要"混合距离"。 Further, for the light from the discrete light source becomes uniform, we need to "mixing distance." 在导光板的边缘处提供用于光混合的足够空间需要在显示器的边缘处有附加的非有效的显示区域。 Enough space at the edge of a light guide plate provided for light mixing is required at the edge of an additional non-effective display area of ​​the display. 将发光二极管定位在导光板的边缘处可因此导致在显示器的边界周围存在不期望的大量非有效的显示区域。 The light emitting diode is positioned at the edge of the light guide plate may thus lead to an undesirably large amount of non-effective display region of the display is present around a boundary.

[0092] 为了使在显示器边界周围的非有效的显示区域的量最小化,可将光源定位在空间高效的位置,并且可使用辅助光导结构将来自光源的光路由至导光板。 [0092] In order to make an effective amount of a non-display region around the display boundaries is minimized, the light source may be positioned in a space-efficient location, and may use the auxiliary light guide structure optical path from the light source to the light guide plate. 例如,光源可位于导光板上方,可位于导光板下方,或可位于不必使用附加非有效的显示区域的居中位置。 For example, the light source may be located above the light guide plate, the light guide plate may be located below, or may be positioned without using an additional non-effective display area centered position.

[0118] 如果需要,可使光导结构96向上压靠导光板32,或可使用粘合剂将光导结构96粘结至导光板32。 [0118] If desired, the light guide structure 96 is pressed against the guide plate 32 upwardly, or may use adhesive bonding the light guide structure 96 to the light guide plate 32. 例如,透明粘合剂诸如透明粘合剂97 (例如,环氧树脂)可插入光导结构96和导光板32之间并且可用于将光导结构96附接至导光板32的边缘。 For example, a transparent adhesive such as a transparent adhesive 97 (e.g., epoxy resin) may be interposed between the light guide structure 32 and the light guide plate 96 and the light guide structure can be used to the edge of the light guide plate 96 is attached 32.

[0119] 如果需要,可相邻于集中式光源38'形成可选散热器结构,诸如散热器结构98,并且可使用该散热器结构将热量转移远离光源38'。 [0119] If desired, adjacent to the centralized light source 38 'form an optionally heat sink structure, such as a heat sink structure 98, and the heat sink structure may be used to transfer heat away from the light source 38'. 散热器结构98可由导热材料诸如金属形成。 Heat sink structure 98 may be formed a thermally conductive material such as metal. 如果需要,散热器结构98可形成为围绕外壳结构或其他结构的整体部分,或可形成为将热量转移远离显示器14的独立结构。 If desired, the heat sink structure 98 may be formed to surround the entire portion of the housing structure or other structure, or may be formed as an independent structure to transfer heat away from the display 14.

[0120] 图13为可用于为显示器14提供背光的另一可能背光组件的顶视图。 [0120] FIG. 13 is used to provide backlighting for the display 14 a top view of another possible backlight assembly. 如图13所示,集中式光源诸如集中式光源38'可用于为显示器14提供背光。 13, a centralized source, such as a centralized source 38 'may be used to provide backlighting for the display 14. 辅助光导结构诸如光导结构96可用于将来自集中式光源38'的光72分布于导光板32的边缘上。 Light auxiliary light guiding structure 96 such as a light guide structure can be used from the centralized light source 38 'is located in the upper edge 72 of the light guide plate 32.

[0122] 图14为示例性背光结构30的顶视图,其示出光导结构96可如何由多个光波导(光导)诸如光波导102形成。 [0122] FIG. 14 is a top view of an exemplary structure of a backlight 30, showing how a light guide such as an optical waveguide structure 96 may be formed of a plurality of optical waveguides 102 (light guide). 如图14所示,光72可传播穿过光波导102并且可发射至导光板32的边缘内。 14, the light 72 propagate through the light waveguide 102 and is transmitted to the inner edge of the guide plate 32. 每个光波导102可耦接至导光板32的相应部分,以使得光72沿导光板32的边缘均匀地分布。 Each of the optical waveguide 102 may be coupled to respective portions of the light guide plate 32, so that the light guide plate 72 uniformly distributed along the edge 32.

[0123] 光波导102可由聚合物诸如环氧树脂形成,可由光纤形成,或可由其他合适材料形成。 [0123] The optical waveguide 102 is formed by a polymer such as epoxy, may be formed in an optical fiber, or may be formed from other suitable materials. 光波导102可具有圆形横截面形状、正方形横截面形状、矩形横截面形状、椭圆形横截面形状、具有弯曲边缘的形状、具有直边缘的形状、具有弯曲边缘与直边缘的组合的形状或其他合适横截面形状。 The optical waveguide 102 may have a circular cross-sectional shape, a square cross-sectional shape, a rectangular cross-sectional shape, an elliptical cross-sectional shape, a shape having a curved edge, the straight edge has a shape having a curved edge and a straight edge shape or a combination of other suitable cross-sectional shape. 如果需要,光波导102可安装至支撑结构诸如支撑结构112 (例如, 刚性或柔性玻璃或塑料基板或树脂层),或可直接安装于外壳结构12或其他支撑结构内。 If desired, optical waveguide 102 may be mounted to a support structure such as support structure 112 (e.g., a rigid or flexible glass or plastic substrate or a resin layer), or may be directly mounted in the housing structure 12 or other support structure.

[0124] 图15为示例性背光结构30的顶视图,其示出光导结构96可如何具有漏光促进结构诸如漏光促进结构104以帮助将光散射出光导结构96并且散射至导光板32。 [0124] FIG. 15 is a top view of an exemplary structure of a backlight 30, showing how the light guide structure 96 may have a structure such as light leakage light leakage promotion structure 104 to help promote the light-scattering light guide structure 96 and the light guide plate 32 to scatter. 例如,可通过使相邻于导光板32的光导结构96的表面(例如,表面114)粗糙化或在该表面中形成凹口来形成漏光促进结构104。 For example, by making the surface of the light guide adjacent to the light guide plate 32 of the structure 96 (e.g., surface 114) roughened or recesses formed in the surface 104 to form a light leakage promotion structures. 当光在光导结构96内传播时,表面114的粗糙化纹理可促进光从光导结构96泄漏至导光板32内。 When light propagating within the light guide structure 96, roughened surface texture 114 may facilitate the leakage of the light guide structure 96 to the guide plate 32.

[0125] 如果需要,可选反射器诸如反射器106可相邻于光导结构96形成于粗糙化表面114的相对侧上。 [0125] If desired, an optional reflector, such as reflector 106 may be adjacent to the light guide structure 96 formed on opposite sides of the roughened surface 114. 在方向108上从光导结构96逸出的任何光均可由反射器106朝向导光板32反射回去。 In the direction 108 is reflected back toward the light guide structure can 96 any light escaping from the light guide plate 32 reflector 106. 反射器106可由白色塑料、金属或其他反射材料的片材形成。 The reflector 106 may be a white plastic, sheet metal or other reflective material.

[0126] 当光72在光导结构96内传播(例如,在方向116上)并且距集中式光源38'的距离增大时,光72的强度可降低。 [0126] When the propagation of light 72 (e.g., in the direction 116) in the light guide structure 96 and from the centralized light source 38 'is the distance increases, the intensity of the light 72 can be reduced. 为了确保光72沿导光板32的边缘均匀地分布,可能需要具有从接收较低强度光的光导结构96部分的增大的漏光。 In order to ensure the light guide plate 72 along the edge 32 are uniformly distributed, it may need to have an increased leakage of light from the light guide structure 96 receiving the lower portion of the intensity of light.

[0127] 为了增大在光导结构96的距离集中式光源38'较远的部分中的漏光,漏光促进结构104可沿表面114的长度不均匀。 [0127] In order to increase the 'distant from the light leakage portion 96 of the light guide structure centralized light source 38, light leakage promotion structures 104 may be non-uniform along the length of surface 114. 例如,漏光促进结构104在光导结构96的表面114上的尺寸、密度和/或形状可随着距集中式光源38'的距离增大而改变(例如,表面114上的粗糙度可沿方向116增大)。 For example, the size of light leakage promotion structures 104 on the surface 114 of the light guide structure 96, the density and / or shape may be centralized with distance from the light source 38 'is increased to change (e.g., roughness on the surface 114 along a direction 116 increase). 这种类型配置可确保光沿导光板32的边缘均匀地分布。 This type of configuration ensures uniformly distributed along the edge of the light guide plate 32.

[0128] 图16至图20为其中光导结构96可具有不均匀漏光促进结构的方式的示例性例子。 [0128] FIGS. 16 to 20 in which the light guide structure 96 may have a non-uniform light leakage promotion exemplary embodiment examples structure.

[0173] 图26中示出了一常规背光布置的横截面侧视图。 [0173] FIG. 26 shows a cross-sectional side view of a conventional backlight arrangement. 如图26所示,通过沿导光板304 的边缘定位的发光二极管302带提供背光照明。 26, light-emitting diodes for backlighting by the light guide plate 304 positioned along the edge 302 of the band. 通常使用焊料将发光二极管302安装至柔性印刷电路基板306。 Is generally used to solder the light emitting diode 302 is mounted to the flexible printed circuit board 306. 由于安装过程期间的放置变化,发光二极管302经常不对准。 Since the change in place during the installation process, the light emitting diode 302 are often not aligned. 结果, 在发光二极管302和导光板304的边缘之间形成气隙G。 As a result, an air gap is formed between the edge of the light emitting diode 302 and the light guide plate 304 G. 此类气隙G可对背光效率具有不利影响。 Such gap G may have a detrimental effect on the efficiency of the backlight. 例如,光308在从气隙G行进至导光板304时将经历折射率的改变。 For example, light 308 travels from the air gap G to the light guide plate will experience a change in refractive index 304. 这样又将改变光308进入导光板304的角度,从而可能抑制导光板304将背光均匀地分布至整个显示器的能力。 This in turn changes the angle of the light 308 entering the light guide plate 304, thereby suppressing the light guide plate 304 may uniformly distribute backlight to the capacity of the entire display.

[0174] 图27中示出了具有气隙的一常规背光布置的顶视图。 [0174] FIG. 27 shows a top view of a conventional backlight having an air gap arrangement. 如图27所示,发光二极管302不对准,从而导致发光二极管302和导光板304之间的气隙G。 As shown, the 27 light emitting diodes 302 are not aligned, thereby resulting in an air gap between the LED 302 and the light guide 304 G. 由于发光二极管302由柔性印刷电路基板306的固体带机械地耦接在一起,因此各个发光二极管302不能够独立地配准至导光板304。 Since the light emitting diode 302 is solid 306 with a flexible printed circuit board are mechanically coupled together, each of the light emitting diode 302 and therefore can not be independently register 304 to the light guide plate. 结果,背光结构300将具有低光学效率。 As a result, the structure of the backlight 300 will have low optical efficiency.

[0176] 背光结构230可安装在可选的支撑结构内,诸如支撑结构262。 [0176] The backlight structure 230 may be mounted in an optional support structure, such as the support structure 262. 支撑结构262(有时称为基座或机械基座)可由诸如塑料、陶瓷、纤维复合材料、金属这样的材料或其他合适材料形成。 The support structure 262 (sometimes referred to as a base or machine base) may be formed such as plastic, ceramics, fiber composites, metal, or other suitable material, such material. 如果需要,可通过将背光结构230直接安装于外壳212内或通过将背光结构230 安装于其他形状的支撑结构中来形成显示器214。 If desired, the display 214 or may be formed by the backlight structure 230 by a support structure attached to the inner shape of the other structures of the backlight 230 is directly attached to the housing 212. 在图28A的示例性配置中,机械基座262 用于形成显示器214的背光组件,该显示器214的背光组件可安装于在显示器覆盖层诸如图25的显示器覆盖层256下方的外壳212内。 In the exemplary configuration of FIG. 28A, the mechanical base 262 for forming a display backlight assembly 214, a backlight assembly of the display 214 may be mounted to the cover layer 25 such as a view of a display housing 212 covers the inner layer 256 at the bottom of the display. 如果需要,可使用其他安装配置。 If necessary, use a different mounting configurations.

[0177] 如图28A所示,发光二极管238可插入柔性尾部260和导光板232之间。 [0177] As shown in FIG 28A, the light emitting diode 238 may be inserted between the flexible tail portion 260 and the light guide plate 232. 每个发光二极管238可具有安装(例如,焊接)至柔性尾部260的基底表面和将光发射至导光板232内的与该基底表面相对的顶表面238T。 Each light emitting diode 238 may have mounted (e.g., welded) to the tail portion of the flexible substrate surfaces 260 and emits light to the inner surface of the light guide plate and the substrate 232 opposite to the top surface 238T. 为了确保发光二极管238压靠导光板232,柔性尾部260可卷曲和/或弯曲以形成弹簧元件,诸如弹簧元件260P。 To ensure that the light emitting diode 238 is pressed against the guide plate 232, flexible tail portion 260 may be crimped and / or bent to form a spring member, such as a spring element 260P. 弹簧元件260P可在方向266上将力施加于发光二极管238 (例如,朝向导光板232)。 The spring element 260P may be applied to the light emitting diode 238 (e.g., toward the light guide plate 232) on the force in the direction 266. 为了使柔性尾部260形成至该类型的弹簧元件内,柔性尾部260可在支撑结构262的内部卷曲。 For the flexible tail portion 260 is formed into the spring element of this type, flexible tail portion 260 may be coiled inside the support structure 262. 在试图返回至其平衡位置(例如,不卷曲)时,柔性尾部260将自然地在方向266上施加力,由此使发光二极管238 的顶表面238T压靠导光板232。 When trying to return to its equilibrium position (e.g., non crimped), will naturally flex tail 260 applies a force in direction 266, whereby the top surface of the light emitting diode 238 of the light guide plate 232 is pressed against 238T. 光可从发光二极管238的顶表面238T直接发射至导光板232的边缘内。 Light may be directly emitted from the top surface 238T light emitting diode 238 to the inner edge of the guide plate 232. 使柔性尾部260形成至使发光二极管238相对于导光板232偏置的弹簧元件内可帮助减小或消除发光二极管238和导光板232之间的气隙。 The flexible tail 260 to form a light emitting diode 238 with respect to the inner spring element to help offset the light guide plate 232 to reduce or eliminate air gaps between the LED 238 and the light guide plate 232.

[0178] 如果需要,弯曲引导结构诸如弯曲引导结构235可任选地用于使柔性尾部260形成和成形至弹簧元件260P内。 [0178] If desired, the curved guide structure such as a bending guide structure 235 may optionally be used in the flexible tail portion 260 is formed and shaped into the spring element 260P. 柔性尾部260可在弯曲引导结构235周围弯曲以在柔性尾部260中形成所需弯曲。 The flexible tail portion 260 may be bent around the guide structure 235 bent to form a desired bend in the flexible tail 260. 弯曲引导结构235(有时称为芯轴)可为适形的或尺寸不够大的结构,并且可由诸如泡沫、橡胶、塑料这样的材料或其他合适材料形成。 Bending guide structure 235 (sometimes referred to as a mandrel) may be conformable structure or size is not big enough, and may be such as foam, rubber, plastic or other such materials suitable material. 例如,弯曲引导结构235可具有细长杆形状,其平行于电子设备10的边缘延伸。 For example, the bending guide structure 235 may have an elongated bar shape, extending parallel to the edge 10 of the electronic device. 在柔性尾部260在弯曲引导结构235周围卷曲时,在弯曲引导结构235上的弯曲表面可用于形成柔性尾部260上的弯曲部分。 In the tail portion 260 when the flexible bending guide structure 235 crimped around the curved surface on the curved guide structure 235 can be used to form a curved portion 260 on flexible tail portion. 如果需要,可在将柔性尾部260操纵至弹簧元件260P内的同时加热弯曲引导结构235。 If desired, can be manipulated to flex tail 260 of the spring element 260P while heating the bending guide structure 235. 弯曲引导结构235可形成为外壳212的整体部分,可形成为支撑结构262的整体部分, 或可为用于使柔性尾部260形成至弹簧元件260P内的独立结构。 Bending guide structure 235 may be formed as an integral part of the housing 212, may be formed as an integral part of the support structure 262, or may be used for the flexible tail 260 to form independent structures in the spring element 260P.

[0181] 如图28B所示,可在柔性尾部260中形成多个间隙,诸如间隙268,由此产生多个分开的柔性"插片"。 As shown in [0181] FIG 28B, a plurality of gaps may be formed in the flexible tail 260, such as gap 268, thereby producing a plurality of separate flexible "tabs." 每个发光二极管238可安装在相关联的柔性插片上。 Each light emitting diode 238 may be mounted on a flexible tab is associated. 间隙268(有时称为槽隙)可将发光二极管238相互分开并且机械去耦,从而允许每一者独立地配准至导光板232。 Gap 268 (sometimes referred to as slots) may be separated from each light emitting diode 238 and the mechanical decoupling, thereby allowing independent registration of each of the light guide plate 232. 如果需要,迹线诸如迹线267可在柔性尾部260的弯曲部分中局部变宽以增强弯曲部分中迹线的强度。 If desired, traces such as traces 267 may be partially widened to increase the strength of the bent portion of the bent portion of the traces of the flexible tail 260.

[0182] 在图28B中,示出柔性尾部260处于平坦位置(例如,"不卷曲")。 [0182] In FIG 28B, the flex tail 260 is shown in a flat position (e.g., "do not curl"). 当柔性尾部260 卷曲成图28A中所示的弹簧元件260P的形状时,每个发光二极管238的顶表面238T将压靠导光板232的边缘。 When the flexible tail portion 260 crimped to the spring element shown in FIG. 28A in the shape 260P, each light emitting diode of the top surface 238T 238 pressed against the edge of the light guide plate 232. 由弹簧兀件260P提供的力可抵靠导光板232向上推动发光二极管238的顶表面238T,并且每个单独的发光二极管238可独立地配准至导光板232。 Wu force provided by the spring member 260P abut against the top surface of the light guide plate driven light emitting diode 232 238T 238 upwards, and each separate light-emitting diode 238 can independently register 232 to the light guide plate.

[0183] 在图28B的例子中,间隙268用于隔离每个单独的发光二极管238 (例如,单个发光二极管238安装在每个柔性插片上)。 [0183] In the example of FIG. 28B, the gap 268 is used to isolate each individual light emitting diode 238 (e.g., a single light emitting diode 238 is mounted on each flexible tab). 然而,这仅是示例性的。 However, this is only exemplary. 如果需要,间隙268可用于隔离发光二极管238组。 If desired, the gap 268 may be used to isolate the group of the light emitting diode 238. 例如,如果需要,在相关联的柔性插片上可存在两个、三个或三个以上的发光二极管。 For example, if desired, there may be more than two, three, or three light emitting diodes on a flexible tab is associated. 一般而言,可使用任何数量的间隙268分开任何数量的发光二极管238。 In general, any number of gaps 268 separate from any number of light emitting diodes 238.

[0184] 图28C为可用于形成图28A的弹簧元件260P的柔性尾部260的另一可能配置的顶视图。 [0184] FIG 28C is formed in FIG. 28A, top view of another spring element 260P flexible tail portion 260 may be configured to be used. 如图28C所示,在上面安装发光二极管238的柔性尾部260可为柔性印刷电路基板的固体带。 As shown in FIG. 28C, a light emitting diode 238 is mounted, flexible tail portion 260 may be a solid with a flexible printed circuit board in the above. 在图28C中,示出柔性尾部260处于平坦位置(例如,"不卷曲")。 In FIG. 28C, flex tail 260 is shown in a flat position (e.g., "do not curl"). 当柔性尾部260卷曲成图28A中所示的弹簧元件260P的形状时,由弹簧元件260P提供的力将抵靠导光板232向上推动每个发光二极管238的顶表面238T。 When the flexible tail portion 260 crimped to the spring element shown in FIG. 28A in the shape of 260P, the force provided by the spring element 260P will push against the top surface of the light guide plate 232 of each light emitting diode 238 238T upward. 光可从发光二极管238的顶表面238T直接发射至导光板232的边缘内。 Light may be directly emitted from the top surface 238T light emitting diode 238 to the inner edge of the guide plate 232.

[0185] 由于每个发光二极管238的顶表面238T配准至导光板232,因此在柔性尾部260 上的发光二极管238的任何放置变化(例如在柔性尾部260的表面上的位置变化)将不影响发光二极管物理接触导光板232的能力。 [0185] Any change in place (e.g., change in position on the surface of the flexible tail portion 260) will not affect the 238 because each light emitting diode 238 of the top surface 238T registration guide plate 232, the light-emitting diode on the flexible tail 260 LED light guide plate 232 contacting physical ability. 由弹簧元件260P提供的力将推动顶表面238T 与导光板232直接接触,而不管在柔性尾部260的表面上的任何横向不对准。 The force provided by the spring element 260P will drive 232 directly contacts the top surface of the light guide plate 238T, and regardless of any transverse surface of the flexible tail 260 is not aligned.

[0186] 图29A为显示器214的一部分的横截面侧视图,示出了可用于使显示器214的光学效率最佳化的另一可能背光组件。 [0186] FIG 29A is a cross-sectional side view of a portion of a display 214 is shown may be used to optimize the efficiency of the optical display 214 according to another possible backlight assembly. 如图29A所示,柔性尾部260可卷曲和/或弯曲以形成弹簧元件260P。 Shown in Figure 29A, the flexible tail portion 260 may be crimped and / or bent to form a spring element 260P. 图29A的弹簧元件260P可在方向272上(例如,朝向导光板232)将力施加于发光二极管238,由此使发光二极管238的侧表面238S压靠导光板232。 FIG 29A is a spring element 260P may be in a direction 272 (e.g., toward the light guide plate 232) a force is applied to the light emitting diode 238, whereby the side surface of the light emitting diode 238 of the light guide plate 232 is pressed against 238S. 光可从每个发光二极管238的侧表面238S(例如,垂直于发光二极管238的基底表面的表面)直接发射至导光板232的边缘内。 Light from the side surface 238S of each light emitting diode 238 (e.g., a light emitting diode perpendicular to the surface of substrate surface 238) is directly transmitted to the inner edge of the guide plate 232.

[0187] 如果需要,弯曲引导结构235可任选地用于使柔性尾部260形成和成形至弹簧元件260P内。 [0187] If desired, the curved guide structure 235 may optionally be used in the flexible tail portion 260 is formed and shaped into the spring element 260P. 柔性尾部260可缠绕在弯曲引导结构235周围以在柔性尾部260中形成所需弯曲。 Flex tail 260 may be wrapped in the flexible tail 260 to form a desired bend around the bending guide structure 235. 为了使在小弯曲半径的区域中柔性尾部260上的应力最小化,柔性尾部260的部分可穿孔,可预先形成(例如,使用热形成过程或冷形成过程),可具有减小的层(例如,柔性电路260的弯曲区域中铜镀覆可减小至一层以增大弯曲区域中的柔性)等。 For the flexible tail portion in the region of small bending radii to minimize stress on the 260, the portion of the flexible tail 260 may be perforated, may be preformed (e.g., using hot or cold forming process forming process), the layer may have reduced (e.g. the flexible circuit 260 in the curved region may be reduced to the copper plating layer to increase the flexibility in bending region) and the like. 在柔性尾部260 的具有小弯曲半径的部分中,可通过增大弯曲区域中迹线的宽度来加强图案化迹线。 In the portion having a small bending radius of the flexible tail 260, may be strengthened by increasing the patterned trace width curved region in traces.

[0188] 如果需要,发光二极管238可相互机械去耦,以使得每个单独的发光二极管238可独立配准至导光板232。 [0188] If desired, the light emitting diode 238 may be decoupled mechanically from each other so that each individual light emitting diode 238 may be independently registered to a guide plate 232. 图29B中示出了其中使用间隙分开相邻发光二极管238的柔性尾部260的顶视图。 FIG 29B shows a top view of the flexible tail portion in which the use of a gap 238 separating adjacent light-emitting diode 260. 如果需要,图29B的柔性尾部260可用于形成图29A的弹簧元件。 If desired, the flexible tail 260 of FIG. 29B may be used to form the spring member of FIG. 29A.

[0189] 如图29B所示,可在柔性尾部260中形成多个间隙268 (例如,矩形槽隙),由此产生多个分开的柔性插片。 [0189] As shown in FIG 29B, a plurality of gaps 268 may be formed in the flexible tail portion 260 (e.g., rectangular slots), thereby producing a plurality of separate flexible tabs. 每个发光二极管238可安装在相关联的柔性插片上。 Each light emitting diode 238 may be mounted on a flexible tab is associated. 间隙268可将发光二极管238相互分开并且机械去耦,从而允许每一者独立地配准至导光板232。 A gap 268 may be light emitting diodes 238 spaced from each other and mechanically decoupled, thereby allowing independent registration of each of the light guide plate 232.

[0190] 在图29B中,示出柔性尾部260处于平坦位置(例如,"不卷曲")。 [0190] In FIG 29B, flex tail 260 is shown in a flat position (e.g., "do not curl"). 当柔性尾部260 卷曲成图29A中所示的弹簧元件260P的形状时,发光二极管238的侧表面238S可与导光板232直接接触。 When the flexible tail portion 260 crimped to the spring element shown in FIG. 29A in the shape of 260P, the light emitting diode 238 side surface 238S can be in direct contact with the light guide plate 232. 由弹簧元件260P提供的力可抵靠导光板232推动每个发光二极管238 的侧表面238S。 The force provided by the spring element 260P abut the guide plate 232 push each light emitting diode 238 side surface 238S. 由于发光二极管238相互机械去耦,因此发光二极管238的不对准将不影响各个发光二极管238物理接触导光板232的边缘的能力。 Since the light emitting diodes 238 are mechanically decoupled, the light-emitting diode 238 does not affect the Commodore respective light emitting diodes 238 in physical contact with the edge of the light guide plate 232 capabilities.

[0191] 在制造期间,可能无意地稍微成角度地将发光二极管焊接至柔性尾部。 [0191] During manufacture, it may inadvertently slightly angled to the light-emitting diodes soldered to the flexible tail. 如果不小心,则此类型的成角度位置可导致发光二极管与导光板之间的气隙。 If not careful, this type can lead to an angled position gap between the guide plate and the light emitting diode. 为了确保发光二极管238与导光板232的边缘齐平,发光二极管238可具有旋转能力。 To ensure that the light emitting diode 238 and the light guide plate 232 is flush with the edge of the light emitting diode 238 may have the ability to rotate. 图29C为其中发光二极管238具有旋转能力的柔性尾部260的顶视图。 FIG 29C is a view in which the light emitting diode 238 has a flexible tail portion 260 of the rotation capability. 如果需要,图29C的柔性尾部260可用于形成图29A的弹簧元件260P。 If desired, the flexible tail 260 of FIG 29C may be used to form the spring member of FIG. 29A 260P.

[0192] 如图29C所示,多个槽隙268可插入相邻发光二极管238之间。 [0192] FIG. 29C, a plurality of slots 268 may be inserted between adjacent light emitting diodes 238. 槽隙268可具有局部变宽的部分,诸如变宽的部分274。 Slots 268 may have a partially widened portion, such as a widened portion 274. 具有带有局部变宽部分的槽隙可允许每个发光二极管238稍微旋转,如由图29C中的箭头276所指示。 With slots having a local widening part may allow each light emitting diode 238 is slightly rotated, 276 as indicated by an arrow in FIG. 29C. 为发光二极管238提供旋转能力可确保每个发光二极管238的整个侧表面238S与导光板232直接接触。 A light emitting diode 238 to provide rotational capability ensures that each light emitting diode 238S 232 in direct contact with the entire side surface 238 of the light guide plate.

[0193] 图30A为显示器214的一部分的横截面侧视图,示出了可使显示器214的光学效率最佳化的另一可能背光布置。 [0193] FIG 30A is a cross-sectional side view of a portion of the display 214 showing the optical efficiency can be optimized in the other display backlight 214 may be disposed. 如图30A所示,柔性尾部260可沿导光板232的边缘平放。 As shown in FIG 30A, the flexible tail 260 along the edge of the light guide plate 232 is flat.

[0194] 粘合剂诸如粘合剂282的层可插入柔性尾部260和支撑结构262之间。 [0194] The pressure-sensitive adhesive such as a pressure-sensitive adhesive layer 282 may be interposed between the flexible tail portion 262 and a support structure 260. 粘合剂282可为将柔性尾部260附接至支撑结构262同时允许柔性尾部260沿支撑结构262的表面进行一些移动的高剪切粘合剂。 Adhesive 282 is a flexible tail portion 260 may be attached to the support structure 262 while allowing the tail portion 260 along the support surface of the flexible structure 262 of some movement high shear adhesive. 高剪切粘合剂诸如粘合剂282可提供将柔性尾部260固定至支撑结构262内部而不限制其在支撑结构262表面上的横向移动(例如,不抑制导光板232和发光二极管238之间的配准)的方式。 High shear adhesive such as the adhesive 282 may be provided between the flexible tail 260 fixed to the support structure 262 without limiting its inner lateral surface of the support 262 is moved in the structure (e.g., does not inhibit the light guide plate 232 and the light emitting diodes 238 registration) manner. 粘合剂282可由压敏粘合剂、UV可固化粘合剂、空气可固化粘合剂、水分可固化粘合剂或其他合适类型的粘合剂形成。 Adhesive 282 may be a pressure sensitive adhesive, UV curable adhesive, an air curable adhesive, moisture curable adhesive, or other suitable type of adhesive. 如果需要,粘合剂282可用作散热器。 If desired, the adhesive 282 may be used as a heat sink. 例如,粘合剂282可由具有高热导率的材料形成,并且可被配置为将热量从背光结构230转移至支撑结构262、外壳212或背光结构30附近的其他合适散热器。 For example, adhesive 282 may be formed of a material having high thermal conductivity is formed, and may be configured to transfer heat from the backlight structure 230 to the support structure 262, other suitable heat sink 212 near the housing 30 or backlight structures.

[0195] 安装在柔性尾部260上的多个发光二极管238可相互机械去耦,以使得每个单独的发光二极管238可独立地配准至导光板232。 A plurality of light emitting diodes [0195] 260 mounted on the flexible tail portion 238 may be decoupled from one another mechanically, so that each individual light emitting diode 238 can independently register 232 to the light guide plate. 图30B中示出了柔性尾部的顶视图,该柔性尾部为可用于图30A的配置中的类型。 FIG 30B shows a top view of the flexible tail, the tail portion is a flexible type that can be used in the configuration of FIG. 30A.

[0196] 如图30B所示,柔性尾部260可具有其中在柔性尾部260的两侧形成间隙的蜿蜒形状。 As shown in [0196] FIG 30B, flex tail 260 may have a serpentine shape wherein a gap is formed on both sides of the flexible tail 260. 例如,间隙诸如间隙268可形成于在相邻发光二极管238之间的柔性尾部260的侧2A上。 For example, the gap 268 may be formed as a gap on the upper side 2A of the flexible tail portion 238 between adjacent light emitting diodes 260. 下一个最近间隙诸如间隙268B可形成于柔性尾部260的侧2B (例如,柔性尾部260 的相对侧)上。 Recently, such a clearance gap next 268B may be formed on the upper side of the flexible tail 260 (e.g., flexible tail portion 260 of the opposite side) 2B. 间隙可沿柔性尾部260的长度在侧上交替,以产生蜿蜒形状的柔性基板。 The length of the gap 260 may be on alternate sides, the flexible substrate to produce a serpentine shape along the flexible tail.

[0197] 当背光结构230插入至支撑结构262A内时,可在方向284上施加力(图30A)。 [0197] When the backlight structure 230 is inserted into the support structure 262A, may apply a force in the direction 284 (FIG. 30A). 这样可将柔性尾部260推动至支撑结构262的后壁262R内,并且减小或消除发光二极管238 与导光板232之间的间隙。 Such flex tail 260 may be pushed into the support structure 262 of the rear wall 262R, and reduce or eliminate the gap between the LED 238 and the light guide plate 232. 由于柔性尾部260的蜿蜒形状(图30B),发光二极管238可相互机械去耦,以使得每个发光二极管238的侧表面238S可独立地配准至导光板232。 Since the flexible tail portion 260 of the serpentine shape (FIG. 30B), the light emitting diode 238 may be decoupled mechanically from each other, so that the side surface 238S of each light emitting diode 238 can independently register 232 to the light guide plate.

[0198] 图31A为显示器214的一部分的横截面侧视图,示出了可用于使显示器214的光学效率最佳化的另一可能背光组件。 [0198] FIG 31A is a cross-sectional side view of a portion of a display 214 is shown may be used to optimize the efficiency of the optical display 214 according to another possible backlight assembly. 如图31A所示,柔性尾部260可沿导光板232的边缘平放。 As shown in FIG 31A, the flexible tail 260 along the edge of the light guide plate 232 is flat. 偏置结构诸如偏置结构292可用于使发光二极管238相对于导光板232偏置,以帮助减小或消除发光二极管238与导光板232之间的气隙。 Biasing structure biasing structure 292 may be used such as a light emitting diode 238 biased with respect to the light guide plate 232, to help reduce or eliminate air gaps between the LED 238 and the light guide plate 232. 偏置结构292可插入发光二极管238和支撑结构262的后壁262R之间。 Biasing structure 292 may be a light emitting diode inserted between the rear wall 262R 238 and support structure 262.

[0199] 如果需要,偏置结构292可由可适形的、导热泡沫(例如,由Gap pacf材料或其他合适材料形成的泡沫)形成。 [0199] If desired, the biasing structure 292 may be conformable, thermally conductive foams (e.g., foam material or by Gap pacf other suitable material). 使用导热材料形成偏置结构292可允许偏置结构292将热量从背光结构230 (例如,从发光二极管238)转移至支撑结构262、外壳212或在背光结构30 附近的其他合适散热器。 Biasing structure is formed using the thermally conductive material 292 may allow heat biasing structure 292 (e.g., from a light emitting diode 238) is transferred from the backlight structure 230 to the support structure 262, the housing 212 or other suitable heat sink structure 30 in the vicinity of the backlight. 可用于使发光二极管238相对于导光板232偏置的其他结构包括金属填充的泡沫、V形结构(例如,V形金属弹簧构件)、弹簧结构、其他合适结构等。 Light emitting diode 238 may be used with respect to other structures including the light guide plate 232 biased metal-filled foam, V-shaped structure (e.g., V-shaped metal spring member), a spring structure, other suitable structure.

[0200] 如果需要,可选粘合剂诸如高剪切粘合剂282可用于将柔性尾部260附接至支撑结构262,而不限制其在支撑结构262表面上的横向移动(例如,不抵抗由偏置结构292提供的偏置力)。 [0200] If desired, an optional adhesive such as a high shear adhesive 282 may be used to flex tail 260 is attached to the support structure 262, without limiting lateral movement on the surface of the support structure 262 (e.g., non-resistance the biasing force provided by the biasing structure 292). 然而,这仅是示例性的。 However, this is only exemplary. 可使用其他方法将柔性电路260附接至支撑结构262。 Other methods may be used to flex circuit 260 attached to the support structure 262. 例如,柔性尾部260的相对端可具有轨道孔。 For example, the opposite end of the flexible tail 260 may have a track hole. 可使用螺钉或销钉在轨道孔处将柔性尾部260固定至支撑结构262。 Using a screw or pin hole of the track of the flexible tail 260 fixed to the support structure 262. 图31B为柔性尾部260的顶视图,示出了轨道孔可如何用于将柔性尾部260附接至支撑结构262。 FIG 31B is a top view of the flexible tail portion 260, shows how a track hole 260 for the flexible tail portion attached to the support structure 262.

[0201] 如图31B所示,孔诸如轨道孔980 (有时称为开口或槽隙)可形成于柔性尾部260 的相对端中。 [0201] FIG. 31B, such as a track hole 980 hole (sometimes referred to as openings or slots) may be formed on the opposite end of the flexible tail portion 260. 销钉诸如销钉960可插入穿过每个轨道孔980。 Such as a pin 960 may be inserted through a pin hole 980 for each track. 销钉960可用于将柔性尾部260紧固至支撑结构262。 960 may be used to pin 260 secured to the support structure of the flexible tail 262. 销钉960可为蘑菇状销钉、直销钉或任何其他合适类型的销钉或螺钉。 Pin 960 may be a mushroom-shaped pins, nails, or any other suitable direct type of pins or screws. 轨道孔980可具有细长"轨道"形状。 Track hole 980 may have the shape of an elongated "track." 柔性尾部260在y和z方向上的移动可受到限制,然而,可允许在x方向上的移动(例如,可允许沿细长轨道孔980长度的移动)。 Flexible tail portion 260 moves in the y and z-directions may be limited, however, may be allowed to move in the x-direction (e.g., 980 may be allowed to move along the length of the elongated track hole). 该类型的紧固方法可提供将柔性尾部260固定至支撑结构262内部而不限制其相对于导光板232的横向移动(例如,不抵抗由偏置结构292提供的偏置力)的方式。 This type of fastening method may provide a flexible tail portion 260 is fixed to the inner support structure 262 without limiting manner with respect to the light guide plate 232 of the lateral movement (e.g., not against the biasing force provided by the biasing structure 292) a.

[0202] 当将背光结构230插入到支撑结构262内时,偏置结构292可在方向294上施加力(例如,偏置结构292可使发光二极管238相对于导光板232偏置)。 [0202] When the backlight structure 230 inserted into the support structure 262, biasing structure 292 may exert a force in the direction 294 (e.g., a light emitting diode biasing structure 292 allows the light guide plate 238 with respect to the offset 232). 由偏置结构292提供的偏置力可减小或消除发光二极管238与导光板232之间的间隙。 The biasing force provided by the biasing structure 292 may reduce or eliminate the gap between the light emitting diode 238 and the light guide plate 232. 如果需要,柔性尾部260可形成为具有蜿蜒形状,如图31C所示。 If desired, the flexible tail 260 may be formed to have a serpentine shape, as shown in FIG 31C. 柔性尾部260的蜿蜒形状可用于使发光二极管238相互机械去耦,以使得每个发光二极管238的侧表面238S可独立地配准至导光板232。 The serpentine shape of the flexible tail 260 may be used to the light emitting diode 238 are mechanically decoupled, so that the side surface 238S of each light emitting diode 238 can independently register 232 to the light guide plate.
